An American civilian who works at Yokosuka Naval Base, Japan, was accused Wednesday of exposing himself to three elementary school girls in the city of Yokosuka, according to Japanese police.

The girls alerted police who apprehended Adam Lewis Liotino, 26, employed by Commander Fleet Activities Yokosuka, a Yokosuka police spokesman said.

Navy officials confirmed a civilian employee of the base Morale, Welfare and Recreation department is in Japanese custody but provided no further comment or details.

“We are cooperating fully with the Japanese police,” said Yokosuka base spokesman Mike Chase.

The girls told police that as they walked home from school about 3:30 p.m., Liotino exposed his lower body to them, the police spokesman said.

The girls ran to get help at the nearest police box and officers returned to the scene and picked Liotino up for questioning.

The spokesman said Liotino told them he had exposed himself to the girls. He was formally arrested on suspicion of indecent public exposure and remained in Japanese custody Friday.

One of the girls told police a man also exposed himself the day before. Police are investigating that incident, the spokesman said.

Under the status of forces agreement, American civilians working for the Department of Defense can be charged by Japanese officials but cannot face penalties by U.S. civilian or military courts.

Yokosuka police sent the case to the District Public Prosecutor’s Office in Yokosuka on Friday. Under Japanese law, the prosecutor’s office determines whether charges will be filed.
